Communication is a fundamental human right, but for many children with autism, expressing
their needs, thoughts, and feelings isn’t always easy through speech alone. That’s where AAC
devices (Augmentative and Alternative Communication) come in, tools that empower children
with autism to communicate effectively, reduce frustration, and build meaningful connections
with the world around them.
Whether a child is nonverbal, minimally verbal, or has delayed language development, AAC
can open doors to social, academic, and emotional growth.
What Is AAC?
AAC stands for Augmentative and Alternative Communication. It refers to any method of
communication used in place of or to support spoken language.
AAC can include:
- Low-tech tools: Picture cards, communication boards, PECS (Picture Exchange Communication System)
- Mid-tech tools: Simple voice output devices (like Big Mack buttons)
- High-tech tools: Speech-generating devices (SGDs), tablets with communication apps like Proloquo2Go, TouchChat, or LAMP Words for Life
For children with autism, AAC isn’t just a backup—it’s often a bridge to developing spoken
language or building a functional, lifelong communication system.
Why AAC Devices Matter for Kids with Autism
Many children with autism struggle with:
- Delayed or absent speech
- Limited expressive language
- Difficulty initiating or sustaining conversations
AAC helps learners by: – Giving immediate access to communication – Reducing frustration and challenging behaviors -Promoting independence and self-advocacy -Supporting language development (yes, using AAC often increases speech—not delays it!)
“Just because a child isn’t speaking doesn’t mean they have nothing to say.”
High-Tech AAC Devices: What Do They Look Like?
High-tech AAC devices often look like iPads or tablets but are equipped with specialized communication software. These systems allow children to:
- Tap symbols or images that represent words
- Use text-to-speech features to produce spoken words
- Create phrases and sentences independently
Popular apps and devices include:
- Proloquo2Go – Highly customizable, symbol-based, ideal for early learners and growing language users
- LAMP Words for Life – Based on motor planning and consistent placement for word selection
- TouchChat HD – Includes voice output and vocabulary building for a range of users
- Tobii Dynavox – A dedicated AAC brand offering devices and software with switch access, eye tracking, and more.
AAC and Autism: Common Misconceptions
“If they use AAC, they’ll never
talk.” Research shows AAC use
supports speech development—
not hinders it.
“AAC is only for nonverbal
kids.” Many verbal children
benefit from AAC for sentence
formation, social interaction, or
academic tasks.
“It’s too early to start AAC.”
AAC can be introduced as early
as 18–24 months, just like
spoken words.
How to Know if a Child Needs AAC
A child may benefit from AAC if
they:
- Are nonverbal or speak less than 20 functional words
- Rely heavily on gestures or crying to communicate
- Repeat phrases (echolalia) but struggle with original speech
- Have difficulty answering questions or expressing wants/needs
- Show frustration due to communication breakdowns Speech-language pathologists (SLPs), BCBAs, and special educators often work together to evaluate AAC readiness
AAC in ABA Therapy
AAC works well in ABA—therapists
can teach vocabulary, reinforce
use, track progress, and support
carryover at home, school, or
clinic.
Goals may include making
requests, combining symbols, and
using AAC for greetings or
comments.
Empowering Kids, Empowering Families
One of the most beautiful moments in therapy is
watching a child hit “I love you” on their device
and seeing their parent tear up with joy. AAC
isn’t just about words—it’s about connection.
Families benefit too:
- Less guesswork
- Fewer meltdowns
- More independence at home and in the community
When a child is given the tools to communicate,
the entire family’s quality of life improves.
